Accelerator Discussion
~~~
The accelerator
is really a combination of several related components. Assuming
that the engine is running, acceleration of the vehicle is accomplished
by the driver depressing the accelerator pedal under his or
her right foot (the longish black pedal on the right-hand side
of the pedal assembly). Depressing the accelerator pedal causes
the accelerator cable to
be pulled forward. This cable runs all the way back into the
engine compartment and connects the accelerator pedal with the
throttle lever on the left side of the carburetor, which in
turn connects with the throttle valve inside the carburetor.
Depressing the accelerator pedal opens the throttle valve and
allows more of the fuel/air mixture to pass into the intake
manifold and on to the cylinders, where it is burned, causing
the engine revolutions to increase and the car to accelerate
(if the transmission is in gear and the clutch pedal is not
depressed).
If the accelerator
pedal is depressed sharply, linkage on the carburetor causes
the accelerator pump to
activate, squirting a spray of fuel directly down the throat
of the carburetor, causing more acceleration.
Note:
If the accelerator pump is adjusted incorrectly, it may cause
stumbling on acceleration. For proper adjustment of the pump,
see our Accelerator Pump Adjustment
procedure.
